WebFeb 17, 2013 · T waves can be peaked, normal, flat, or negative. Flat and negative T waves are defined as: flat T wave < 0.5 mm negative or positive T wave in leads I, II, V3, V4, V5 or V6 negative (or inverted) T wave > 0.5 mm negative T wave in leads I, II, V3, V4, V5 or V6. A concise list of possible causes of T wave changes: Ischemia and myocardial infarction WebThe criteria include the following properties: i) Biphasic or deep inversion of T waves, particularly in leads V2-V3 or in leads V1, V4, V5 and V6; ii) a normal or minimal elevation of the ST-segment and cardiac enzymes; iii) previous experience of angina i) normal Q waves and precordial R-wave progression .

Left ventricular hypertrophy causes increased R-wave amplitudes in V4–V6 and deeper S-waves in V1–V3. Right ventricular hypertrophy causes large R-waves in V1–V3 and smaller R-waves in V4–V6. WebSep 11, 2024 · The normal P wave morphology is upright in leads I, II, and aVF, but it is inverted in lead aVR. The P wave is typically biphasic in lead V1 (positive-negative), but when the negative terminal component of the P wave exceeds 0.04 seconds in duration (equivalent to one small box), it is abnormal.
